MACHINE FOR MAKING COlLED-PAPER TUBES.

srnorrrcn'rron forming part of Letters Patent No. 586,054, dated July 6,1897.

Application filed October 9, 1896.

To all; whom it may concern:

Beitknown that I, HENRY A. NOBLE, a citizen of the United States,residing in Philadelphia, Pennsylvania, have invented certainImprovements in Machines for Making Coiled- Paper Tubes, of which thefollowingis a specification.

My invention consists of certain improvements in paper-tube machineswhereby sucro ccssive strips of paper are spirally coiled one uponanother and the superposed layers secured together by the action of thespiral run of an endless belt, of which any desired number may be used,the object of my invention r 5 being to provide for readily changing thean gle of the presserbelt or belts without slackening or tightening thesame or stopping the machine.

In the accompanying drawings, Figure 1 is a side elevation of apaper-tube machine constructed in accordance with my invention. Fig. 2is a plan or top view of the same. Fig. 3 is a transverse section on'theline as 00, Fig. 1; and Fig. 4 is a plan or top view of a modi- 2 5 fledconstruction of part of the machine.

The fixed frame or bed of the machine may be constructed in anyavailable manner, this element of the machine consisting in the pres entinstance of a pair of channel bars 1,

mounted upon suitable lugs 2 and having at one end a structure 3, whichcarries the hollow spindle 4, to which is suitably secured one end ofthe mandrel 5, upon which the tube is formed and from which it isdelivered 3 5 as produced, the outer end of the mandrel beingunsupported. Turning loosely upon the spindle 4 are a pair of pulleys 6and 7, the pulley 6 receiving the belt 8 from a pulley on anyavailabledrive-shaft. The hub of 4.0 the pulley 6 has secured to it a spur-pinion9, which meshes with a spur-wheel 10, turning loosely upon a stud 11,carried by an arm 12, projecting from one side of the structure 3.

Secured to the spurwheel 10 and turning loosely with it upon the stud 11is a spurpinion 13, which meshes with a spur-wheel 14 on a shaft 15,said shaft being adapted at one end to a bearing in the arm 12 and atthe other end to a bearing in an arm 16, projecting from the bed of themachine at the opposite end of the same. Splined upon the shaft SerialNo. 603,876. (No model.)

15 are bevel-pinions 17, which mesh with bevel-wheels 18 at the lowerends of vertical shafts 19, the latter being free to turn in bearings20, mounted upon transverse bars 21, which rest upon the opposite bars 1of the fixed frame of the machine and have depending bolts 22, passingthrough bars 23, the latter bearing against the under sides of the bars1 and the bolts being provided with nuts 24:, which when tightened serveto secure the transverse bars 21 seeurelyin the position to which theyhave been adjusted longitudinally upon the bars 1.

Upon each of the transverse bars 21 is pivotally mounted a swinging bar25 by means of a bolt 26, these bolts being in line axially with theshafts 19, and the outer end of each of the swinging bars 25 carries aclamp 27, engaging with a segmental rib 28, formed upon thecorresponding bar 21, the stem of the clamp being threaded and providedwith a nut 29, so that either of the swinging bars 25 can be adjustedupon its carrying-bar 21 and secured in position after adjustment.

Longitudinally guided upon ways at the outer end of each of the swingingbars 25 is a slide 30, which has bearings for a vertical shaft 31 andalso for a horizontal shaft 32, the inner end of this latter shafthaving a bearing in a post near the inner end of the swinging bar 25.Each shaft 32 has at the inner end a bevel-pinion 34, meshing with thebevel-wheel 18 of one of the shafts 19, and at its outer end abevel-pinion 35, meshing with a bevel-wheel 36 at the lower end of oneof the shafts 31, said bevel-pinions 35 being splined upon the shafts32, so that adjust ment of the slide 30 upon the swinging bar 25 can bereadily effected.

Each pair of shafts 19 and 31 carries a pair of belt drums or pulleys 37and 38, to which is adapted a belt 39, which runs from the right-handside of one pulley to, over, and around the mandrel 5 and thence to thelefthand side of the opposite pulley, the return run of the beltcrossing from pulley to pulley above the mandrel and being twisted inits course, so as to clear said mandrel, as shown in Fig. 3.

That portion of each belt 39 which surrounds the mandrel 5 follows aspiral course,

the angle of which is dependent upon the adj ustment of the pulleys 37and 3S angularly in respect to each other, and this is effected byswinging upon the bar 21, the bar carrying the outer pulley-shaft 31,the shaft 19 constituting the fixed shaft of the pair, and the axis ofsaid shaft being the axis on which the frame 25 swings in effectingangular adjustment of the pulleys in respect to each other, so that saidangular adjustment can always be varied without slackening or tighteningthe belt 39 or stopping the machine, thus overcoming an objection towhich previous machines of this class with which I am familiar aresubject.

In order to slaeken or tighten the belts 39 to adapt them for actingupon tubes of different diameters, the slides are adjustedlongitudinally upon the swinging bars 35, such adjustmentbeingeifectedby means of screws having hand-wheels 40 in a manner similar to thatadopted in effecting adjustment of the tool-carriages of lathes and likemachinery.

A bracket 41, mounted upon one of the side bars 1 of the main frame ofthe machine, carries at its upper end a guide 42 for the strip of paper43, which forms the primary coil of the tube, said strip 43 being laiddirectly upon the mandrel 5, as shown in Fig. 2.

A red 44 is carried by arms 45 and 46, and upon this red 44 are mountedguides 4'7 and 48 for the strips 49 and 50, which form, respectively,the intermediate and outer coils of the tube which is being produced,these strips being coated with some suitable cement upon the under sidebefore reaehin g the machine.

The strip 49 is subjected to the action of the first presser-belt 39 andis thereby pressed firmly upon the primary or inside coil of the tube, asecond strip 50 being subjected to the action of the second presser-belt39 and being thereby pressed firmly upon the second or intermediatelayer, the finished tube passing from the outer end of the mandrel 5 tosuitable cutting mechanism, whereby it is severed into lengths of theproper size.

Other strips may be fed to the tube between the presser-bclts or thenumber of presserbelts may be increased, as circumstances may suggest.

Although I prefer to mount the shafts 31 upon swinging bars pivotedconcentrically with the shafts 19, such construction is not absolutelyessential to the proper carrying out of the main feature of myinvention. For instance, in Fig. 4 I have shown a modification in whichthe swinging frame 25 is dispensed with, the main transverse frame 21having a central bevel-wheel 51, which turns on an axis concentric withthe bolt 22, this bevel-wheel meshing with a pinion 17 on a shaft 15, towhich said pinion is splined so that it can be moved with the bar 21longitudinally on the main frame, but will always rotate with said shaft15. lVith the bevel wheel 51 also en gage bevel-pinions 52, carried byshafts 0-4 which have bevel-pinions 94 and meshing, respectively, with abevelwheel 18" on a shaft 19 at one end of the bar 21 and with abevel-wheel 36 on a shaft 31 at the opposite end of said bar. It will beevident that in this case the swinging of the bar 21" upon the axis ofthe bevel-wheel 51 will not affect the relative position of the partscarried by said bar. Hence the construction will attain the same resultas that shown in Figs. 1, 2, and 3. The bearings for the shaft 31 andpinion 35 are preferably carried by a slide 30, so as to provide for themovement of said shaft 31 from and toward the shaft 18 in order toslacken or tighten the winding belt.

It will be observed that in both of the c011- struetions shown the axison which the swinging bar turns is concentric with the axis of theprimary wheel of the power-transmitting gear, this wheel in theconstruction shown in Figs. 1, 2, and 3 being the bevel-wheel18, and inthe construction shown in Fig. 4 being the bevel-wheel 51.

Having thus described my invention, 1 claim and desire to secure byLetters 1atent- 1.
